Decreased firing of striatal neurons related to licking during acquisition and overtraining of a licking task.

2 Nov 2009 Neurons that fire in relation to licking, in the ventral part of the dorsolateral striatum (DLS), were studied during acquisition and performance of a licking task in rats for 14 sessions (2 h/d). Task learning was indicated by fewer errors of ... Read more...

Neuroligin-2 deletion selectively decreases inhibitory synaptic transmission originating from fast-spiking but not from somatostatin-positive interneurons.

2 Nov 2009 Neuroligins are cell adhesion molecules involved in synapse formation and/or function. Neurons express four neuroligins (NL1-NL4), of which NL1 is specific to excitatory and NL2 to inhibitory synapses. Excitatory and inhibitory synapses include ... Read more...

Dynamic encoding of movement direction in motor cortical neurons.

2 Nov 2009 When we perform a skilled movement such as reaching for an object, we can make use of prior information, for example about the location of the object in space. This helps us to prepare the movement, and we gain improved accuracy and speed during ... Read more...
